中文摘要：

应用组织学和组织化学方法研究了黑斑蛙（Rana nigromaculata）肾的显微结构。结果表明,黑斑蛙的肾除具有肾单位和集合小管外,还见有淋巴样组织分散于肾实质中。在肾腹侧发现有与真骨鱼类斯坦尼斯小体相似的结构,其中聚集有较多的肥大细胞。说明黑斑蛙的肾具有多种生理功能。

英文摘要：

This paper describes the kidney microstructure of Rana nigromaculata. Histological and histochemical observation showed that besides nephrons and collecting tubes, lymphoid tissues could be observed in the kidney. Moreover,a structure that was similar to the corpuscle of Stannius of teleost was found at the ventral side of the kidney. Numerous mast cells could be observed in that structure as well,suggesting that the kidney of R. nigromaculata is a multifunctional organ.
